- Caddy serves IP addresses and local/internal hostnames over HTTPS with locally-trusted certificates. Examples: `localhost`, `127.0.0.1`.
- Caddy serves public DNS names over HTTPS with certificates from [Let's Encrypt](https://letsencrypt.org). Examples: `example.com`, `sub.example.com`, `*.example.com`.
Caddy keeps all certificates renewed, and redirects HTTP (default port 80) to HTTPS (default port 443) automatically (provided [Activation](/docs/automatic-https#activation) is successful).

Caddy implicitly uses the HTTPS port (default 443) for your [server addresses](/docs/conventions#network-addresses) that don't specify a port explicitly (which would disable automatic HTTPS).
The global setting `auto_https` has two values:
- `disable_redirects` adds an implicit HTTP port redirect.
- `off` disables automatic HTTPS, default implicit port changes to HTTP for all server addresses.
Automatic HTTPS can be configured via the Caddyfile with the [`auto_https` global option](/docs/caddyfile/options), or via [per-server JSON configuration](/docs/json/apps/http/servers/automatic_https/). The Caddyfile option can be set to either of the following:
- `disable_redirects` which disables the implicit HTTP->HTTPS redirect.
- `off` which disables automatic HTTPS altogether, including the HTTP->HTTPS redirect and automatic enabling of TLS for sites that meet the requirements.

### Disabling automatic HTTPS
For local development environments, you can prevent serving via HTTPS by providing an explicit port assignment(disable per server address) or using the global `auto_https off` setting which will change Caddy's implicit port to be the HTTP port (default 80) globally.
For local development environments, you can prevent serving via HTTPS by either specifying `http://` or providing a non-HTTPS port to disable per site, or by adding `auto_https off` to the Caddyfile global options which will change Caddy's implicit port to be the HTTP port (default 80).
